5 Claims. (Cl. 126-242) The present invention relates to improvements in furnaces, more particularly to warm air heating furnaces of the type ,employed to heat air to be supplied to the rooms of a dwelling or the like, although not limited to this type of furnace.

Heretofore, in arranging the fuel for eicient operation in the firepot of a furnace or heating apparatus of the character indicated, lit frequently became necessary to remove hot smoking clinkers therefrom in order to bring the fire in the repot to a satisfactory condition. This was usually accomplished by removing the clinkers from the i'lrepot, followed by placing same in an open receptacle or on the basement floor, with the attendant emission from the clinkers of offensive, odorous gases, smoke and dust, all of which iilled the aforementioned basement. This not only littered up the furnace room, but proved to be injurious to the health of the furnace attendant and generally not conducive to a clean and efficient operation of the furnace.

One of the primary objects of the present invention, therefore, is to provide means forming an integral part of the furnace for receiving the clinkers removed from the repot so that the smoke, odorous gases and dust do not enter the furnace room.

Still a further purpose is to construct a furnace having a receptacle to specially4 receive the clinkers removed from the repot of said furnace.

Yet a further aim is to provide a furnace having a receptacle for receiving hot clinkers, so arranged that the gases, smoke and dust rising therefrom will pass oi through the flue of the furnace without any leakage into the building in which the furnace is located.

Another object of the invention is to provide a furnace with a housing, the latter characterized by a chute and clinker-receiving receptacle, whereby there results a clean, convenient .and healthful means of removing and disposing of hot clinkers.

The above and other aims and purposes will be apparent from the detailed description hereinafter appearing, when read in conjunction with the accompanying drawings showing one embodiment of the invention, and in which,

Figure 1 is a perspective view of a hot air furnace showing the invention applied thereto and with the fuel-feeding door and the door for the receptacle-holding portion of the casing of the invention in open position.

Figure 2 is a perspective view of the housing or casing of the invention prior to attachment 5 Referring for a moment to Figure 1, there is shown a furnace, designated generally as F, and including a combustion chamber 5 having a' dome-head 6, stoker extension 1, right side radiator 8 connected to chamber 5 by extension 9, and left side radiator I 0 secured to the chamber by extension I I. Up to the present the structure described is more or less conventional and forms no part of the novel improvement. Attached forl wardly of the furnace, that is to that portion thereof normally having a fuel-feeding and clinker-removal opening, is a housing o`r casing I5 which is preferably arc-welded to the combustion chamber 5. By reference to Figures 2 and 3 it will be noted that the casing I 5 is composed of an upper section I6 connected by a chute I1 to a bottom or lower section I8, the latter adapted to receive a receptacle I9. The section I6 is-a box-like structure having a top 20 and opposed side walls 2| and 22, while the bottom wall 23 has an opening 24 substantially centrally thereof, leading to the chute I1. The latter constitutes a conduit leading to the lower section I8 which has side walls 25 and 26 and a lower wall or bottom 21 and a rear wall 21a. From the above description it will be apparent that the section I6 is. open at its rear and that this section is in alignment 'with the fuel-feeding opening of the furnace F. Covering the front of upper section I6 is a front wall member 29 which may be permanently connected thereto as by riveting, arcwelding or the like. 'I'he wall 29 is provided with an opening 30 closed by hinged door 3|. Similarly the front of the lower section I8 is equipped with a front wall 32 having an opening normally closed by a hinged door 33. Walls 29 and 32 have aprons which meet in an overlap 32. As indicated, receptacle I9 is open at its top, rests on the bottom wall 21 of the section I8 and is capable of being drawn forwardly through the opening closed by door 33, by means of a handle 34 or the like pivoted onthe receptacle.

In the use of the invention and when it is desired to improve the condition of 'the fire bed in the furnace, the door 3I is swung to open position and the bed reached in the usual manner. Clinkers may be raked or lifted forwardly into the section I6 and then dropped through chute I1 into clinker receptacle I9. During this operation door 33 will remain closed, and after the clinkers have been removed door 3| may also be closed, which will permit the smoke, odorous gases and dust from the clinkers to pass off through the ue of the furnace. Then may follow the addition of fuel to the re bed through the opening closed by door 3 I. After the 'clinkerreceiving receptacle I9 has become filled, door 33 is opened, the clinkers emptied from the receptacle and the latter replaced in position for further use.

From the above description it will be apparent that there has been provided novel means well adapted to permitl the removal of clinkers from the firepot of a furnace without the usual inconveniences normally attending this operation. Although a. preferred embodiment of the invention has been shown and described, it will be. appreciated that numerous changes and variations may be made in structural details, and it is my intention to cover all such and to be limited in this respect only as may be necessary by the scope of the claims hereto appended;

I claim:

1. In a furnace, a combustion chamber having a fuel-feeding and clnker-removal opening, a housing secured to said chamber in direct communication with said opening, and removable means within said housing for receiving clinkers removed from said chamber through said opening, said housing including means for guiding the clinkers to said removable means.

2. In a furnace, a combustion chamber having a fuel-feedingand clinker-removal opening, a housing secured to said chamber in direct communication with said opening, a receptacle within said housing, the latter including means for directing clinkers removed from said chamber through said opening to said receptacle.

3. In a furnace, a combustion chamber having a fuel-receiving and clinker-removal opening, a housing secured to said chamber in direct communication with said opening, said housing having upper and lower sections and a chute connecting same, and a receptacle in the lower section beneath the chute.

4'. In a furnace, a combustin chamber having a fuel-receiving and clinker-removal opening, a housing secured to said chamber, said housing having upper and lower sections and a chute connecting same, the upper section open at its rear and said open portion being aligned with said opening.

5. An attachment for furnaces and the like.
